我创建了一个MarkupExtension
,它公开了类型IValueConverter
的Converter属性,visual studio中的Intellisens找到了它,但是当我尝试编译时,我收到以下错误:Unknown property 'Converter' for type 'MS.Internal.Markup.MarkupExtensionParser+UnknownMarkupExtension' encountered while parsing a Markup Extension.
EnumItemSourceBinding:
Public Class EnumItemSourceBinding
Inherits MarkupExtension
Implements INotifyPropertyChanged
Private mEnumType As Type
Private mConverter As IValueConverter
<DefaultValue(CObj(Nothing))>
Public Property EnumType As Type
Get
Return mEnumType
End Get
Set(value As Type)
mEnumType = value
OnPropertyChanged(NameOf(EnumType))
mBindingChanged = True
End Set
End Property
<DefaultValue(CObj(Nothing))>
Public Property Converter As IValueConverter
Get
Return mConverter
End Get
Set(value As IValueConverter)
mConverter = value
OnPropertyChanged(NameOf(Converter))
mBindingChanged = True
End Set
End Property
Public Event PropertyChanged As PropertyChangedEventHandler Implements INotifyPropertyChanged.PropertyChanged
Public Sub New()
MyBase.New()
End Sub
Public Sub New(enumType As Type)
MyBase.New()
mEnumType = enumType
End Sub
Private Sub OnPropertyChanged(ByVal propertyName As String)
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(propertyName))
End Sub
End Class
的Xaml:
{local:EnumItemSourceBinding {x:Type local:BoundTextFields}, Converter={StaticResource EnumToTextConverter}}
为什么会出现编译错误?
答案 0 :(得分:0)
您似乎无法在要使用它的同一个程序集中定义MarkupExtension
,所以我不得不拆分它。
